UAS regulatory sequences drive expression of the N-terminal part of Abp1 (containing the ADF-H and helical domains), which is tagged with a myristoylation motif (Tag:Myr(Src64B)).
Expression of Abp1N-term.Scer\UAS.T:Myr-Src64B under the control of Scer\GAL4sca.PU does not result in a split microchaete phenotype.
